How to Clean a Trampoline and Outdoor Play Equipment

Outdoor play equipment — trampolines, swing sets, cubby houses, slides and climbing frames — is a permanent fixture in many Adelaide backyards and, by its nature, sits exposed to the weather year-round. It's also among the most neglected items in routine household cleaning, despite direct, frequent contact with children's skin (often bare feet and hands) and, in the case of trampolines specifically, periods of intense physical contact.

This guide covers a practical cleaning approach that addresses both hygiene and material longevity.

Why This Matters Beyond Appearance

Direct skin contact: Children using outdoor play equipment, particularly trampolines (bare feet on the mat, hands on padding and net), have direct, often prolonged skin contact with surfaces that accumulate dirt, mould, bird droppings, and general outdoor grime over time.

Mould and mildew development: Trampoline mats, padding and safety nets, along with the fabric and timber elements of cubby houses, develop mould readily given constant outdoor exposure to moisture (rain, dew, humidity) without the regular drying cycle that, for instance, outdoor furniture cushions might get if brought inside periodically.

Material degradation: Beyond hygiene, regular cleaning extends the functional life of outdoor play equipment — UV-related material breakdown is accelerated by accumulated grime trapping moisture against surfaces, and rust on metal components progresses faster when dirt and moisture sit undisturbed.

Trampolines

The Jumping Mat

1. Sweep off loose leaves, twigs and debris with a broom or stiff brush.
2. Hose down thoroughly to remove dust and loose dirt.
3. Apply a mild detergent solution (dish soap diluted in water) and scrub with a soft-bristle brush, working in sections.
4. For mould spots (commonly appearing as black or green discolouration, particularly in shaded areas of the mat or where leaves have sat and decomposed), a diluted bleach solution (1:10 with water) applied to the affected area, left for 10–15 minutes, then scrubbed and rinsed thoroughly.
5. Rinse the entire mat thoroughly with the hose.
6. Allow to air dry completely before use — a wet trampoline mat is also a slip hazard, separate from the hygiene consideration.

Safety Net and Padding

1. Wipe down with a damp cloth and mild detergent solution, or for more thorough cleaning, hose down and scrub with a soft brush similar to the mat treatment.
2. Pay particular attention to the padding sections (covering the springs), which often show the most significant grime and mould accumulation given their position and the fact they're handled frequently by children climbing on/off.
3. For mould on netting or padding, the same diluted bleach approach as the mat works, with thorough rinsing afterward given the close skin contact this material receives.
4. Allow to fully air dry — netting and padding can retain moisture in their structure longer than the flat mat surface, so check thoroughly before considering the job complete.

Frame and Springs

1. Wipe down the frame with a damp cloth, checking for any rust development.
2. For surface rust on the frame, a wire brush followed by a rust-inhibiting touch-up paint (specifically rated for outdoor/weather exposure) addresses the issue and prevents progression.
3. Springs themselves don't typically need cleaning beyond a general hose-down, but checking for rust or wear during the cleaning process is a useful safety check to bundle in — significantly corroded springs are a safety issue, not just a cosmetic one.

Frequency

A full trampoline clean 2–3 times per year (more frequently if mould is a recurring issue in a shaded yard position) is a reasonable standard for most Adelaide households, with a quick visual check and spot-clean of any obvious mess more frequently.

Swing Sets and Climbing Frames

Plastic Components (Slides, Swing Seats, Climbing Elements)

1. Hose down to remove loose dirt and dust.
2. Wash with a mild detergent solution, scrubbing with a soft brush, paying attention to any textured or grooved surfaces where grime accumulates more than on flat areas.
3. For chalky, faded plastic (UV degradation, similar to the outdoor furniture issue covered in our outdoor furniture guide), a plastic restorer product can improve both appearance and slow further degradation.
4. Check slides specifically for any cracking or sharp edges developing from UV-related brittleness — a safety check worth incorporating into the cleaning routine.

Timber Components

1. Wash with mild detergent solution, scrubbing gently with the grain.
2. Check for splinters, particularly on handrails and any frequently gripped surfaces — sand back any rough areas identified.
3. If the timber has a protective coating (paint, stain, sealant), assess its condition during cleaning and plan for recoating if it's showing significant wear, as exposed, untreated timber on play equipment deteriorates faster and develops splinter risk more readily.

Metal Chains and Fixtures (Swing Chains, Bolts)

1. Wipe down and check for rust, particularly at connection points and any areas where the protective coating may have worn from friction (swing chain links rubbing against connection points is a common wear site).
2. Surface rust can be addressed with a wire brush and touch-up treatment as covered above for trampoline frames.
3. Check that all bolts and fixtures remain secure during this process — again, a practical safety check that naturally bundles with the cleaning routine.

Cubby Houses

Exterior

Treat per our exterior cleaning principles and outdoor furniture guide, scaled to the cubby's specific materials (most are timber, sometimes with plastic roof elements).

Interior

Cubby house interiors, given they're enclosed and often have limited ventilation, can develop mould and mustiness particularly after wet weather if any water ingress occurs through gaps or an inadequate roof seal.

1. Sweep out leaf litter, dirt and any insect activity (spiders commonly establish in cubby house corners given the sheltered, undisturbed conditions).
2. Wipe down interior surfaces with a mild detergent solution.
3. Check for and treat any mould development, particularly in corners and along the floor where moisture might pool if water ingress has occurred.
4. Address any water ingress issue at the source (a gap in the roof or wall join) rather than just treating the resulting mould repeatedly — the same principle covered in our structural vs cleaning issue guide applies here.

Bird Droppings and Outdoor Equipment

Outdoor play equipment, being a prominent elevated structure in many yards, attracts bird activity and consequent droppings on surfaces.

Treat per the bird dropping guidance in our concrete and paving guide — fresh droppings rinse away readily; set, dried droppings benefit from softening with water before removal to avoid simply scraping at a hardened, acidic deposit that can etch or stain the underlying surface, particularly relevant for plastic play equipment surfaces.

A Practical Maintenance Schedule

Monthly (in regular use seasons): Quick visual check and spot clean of any obvious mess, bird droppings, or developing mould.

Quarterly (or 2–3 times yearly): Full clean as detailed above for whichever equipment you have — trampoline, swing set, cubby house.

Before summer (particularly relevant given increased outdoor play time): A thorough clean and safety check timed to align with increased usage as warmer weather arrives.
